IMPROVEMENT IN HOSE-GOUPLINGS.

'ro vALL WHOM IT MAY OONOERN:

Be it knowny that I, ROBERT JOHN GArNus, of Portland, in the eountyof Middlesex, and State of Conneetieut, have invented a new and improved Hose-Coupling; and I do hereby declare that the following is a full and exact description'v thereof, reference being had to the ae'companying drawings, and to thel letters of reference marked thereon. 4 I

The deviceeonsists in'providing the outside ofthe male part of the coupling with two lugs, one upon each side, and directly opposite each other, which lugs run from tho shoulder, upon this'part, to the lface-end, or the endthat is inserted into the female part of the coupling, and atllthislatter extremity the lugs are constructed so as to form a catch. This catch is about'one-half of an inch inlength, and is formed by simply carrying this end offthe'v-lug up at right angles to the rest of it (the lug) abutvone-fou'rth of an inch, and one end of the male part has a screw-thread upon it for the purpose, as in all couplings of hose, vof-screwing it into the end oftheho'se.

And 4thedeviee further consists in providing the female part with a strong shoulder, upon the face-end of it, (the expression, face-end, isused in contradistiuction to theY screw-end of the part,)r,and also a movable band or ring-,which plays upon the outside of this parlt andis lkept upon it, and prevented from playing only within a limited space, by means of two little screwe, on opposite sides of the' ring, which pass entirely through the ring, and project alittle distance beyond the inside of the ring into grooves, upon the body of the female part, outside of it, andunder the movable ring.V These grooves, two iii-number, one upon-each side of this part, go'only partly round, and thus, by nid of the screws before n'ie'ntione'd, the ring is prevented from turning 'only to so far as the grooves extend; and the female part ofthe coupling'is further provided with two slots, (which are also a part ofthe device,) upon the inside of it, onefupon each side, and directly opposite each other. lThese slots runlengthwise of this part, and are cut-from the faceend through nearly to a shoulder formed upon the inside of and at the back of this part, roomjsumciont being loft between the end of the slot and the shoulder last mentiouedfor a thin piece' of rubber or other packing. After-,those slots pass the shoulder upon the faceend of the female part, (whichshoulder is upon the outside of it,) they-cut entirely through the body of the' femalefpart, and also eut the inside of the movable ring, slotting it. And those slots, after passing under the ring, extend beyond it far enough (they being about eue-half of an inch wide) to make an opening large enough to permit the catches upon the lend of the lugs on the male part to come through, when theparts are put together; And into these slots the lugs on the male part pass when the parts are put together.

The device further consists in providing, upon the outer or visible edge of the'movable band 'or ring, two

inclined planes, which planes run from slot to slot, in the-same direction. These inclined planes aro made upon the ring for the purpose of setting up the joint firmly, and of holding the parts when placed together; for the -female part is provided with the strong shoulder, before referred to, and the Auialevpart is provided with the catches upon the ends of the lugs, which catches, when the parts are put together, come through the opening Vor slot made through the body of the female part, just back of the movable ring, and rise above the surface of the female part onefourth of an inch. This brings the movable ring between the strong shoulder of the fema e part and the catches'on the rendsof the lugs on the male part, and when thering is turned in the opposite direction from which the inclined planes run, the ring presses between the shoulder and the catches, and the further the rin-g is turned, -the more firmly the joint is set up, and the more rmly the parts are held together.- The femalepartl is also provided with a screw-thread upon one cud, for the purpose of screwing it into the hose, as are all hose-couplings.

To enable others skilled in the art to make and use my invention, IWill proceed to describe its construction and operation, referring to the drawings which make a part of this specification. l v

The coupling-is made of brass, and the malepart, represented by Figure 1 of the drawings, is provided with lugs, two in number, upon the outside of it, and shown byAA A of hg. 1, which lugs run from the shoulder O 0 of g. 1, to its face or 'inside end, and terminating with the catches K K ofthe iig. .1, which are formed submezz 2 stantially as hereinbefore described, being about one-half an inch long, and about thesame in width. The lugs are about one-fourth of an inch high, and about .one-half of an inch in width. The female part is provided with a strong shoulder, F F F, of Figure 2,l which represents `the female part, which shoulder is upon the outside of it, at the face-end, and it is also provided with a movable ring or band, G G G, of fig.v 2, which plays upon the` outside ofthe female part, and is kept in its place, vand prevented from playing only within a limited space, by means` of two little screws on' opposite sides of the ring, one of which is shown by'l), in hg. 2, which pass entirely through the ring, and project a little distance beyond the inside of the ring, into grooves provided upon the outside of the female part and immediately beneath the movable band or ring, and by those grooves and these-screws the ring is kept in its place, and kept from turning only in a limited space.` The grooves only run partway around the female part, commencing at a slot and running to a slot. Hence the ring can turn only so far as the grooves run. .The female part is further provided with two slots, as represented by B B B,.

of iig. 2, upon the inside of it, one upon each side. These slots run lengthwise of this part, and are cut through from the face-ond nearly to the shoulderv formed upon the inside of .and at thcobaclc of this, the female part, room being left for a piece of packing, ns before shown.` After these slots pass the shoulder F F F, in iig. '2, they cut entirely through the body Aof the female part, and also cut the inside of the ring G G G, slotting it. And these slots, after passing under the ring, extend beyond it,vas is shown by B of fig. 2, far enough, they being about one-half of an inch wide, to make'an opening large enough, as is shown by the same, B', ot' fig. 2,

to permit the catches K K of iig. 1 to come through, when the parts are put together. And into these lslots B B B', of fig. 2, the lugs A A pass when the parts are put together. v

The movable ring or band is provi'd'ed upon 'the outer or visible edge with two inclined planes, one of which is shown by E E of fitr. 2 of the drawings, which planes run from slot to slot upon the edge of the ring, in the same direction as hereinbefore described, and for the purpose hereinbefore set forth. 'lhese inclined planes are constructed upon the edge ofthe ring.

Figure 3 ofthe drawings represents the parts of the coupling put together, and with the joint setup. F F F of fig. 3 represent a strong shoulder on female part of the coupling, and letter A, in fig. 3, shows the catch on thc male partwhich comes through the opening or slot, and rises above the surface of the female part onc-fourth of an inch. Letters G G G of fig. 3 represent the movable ring turned between thecat-ch A and the shoulder F F F ot' fig. 3, and holding the parts firmly together. The movable ring is provided with lugs, so that a wrench may be used, if necessary, in tightening `the joint.

What I claim as" my invention, and desire to secure by Letters Patent, is

A hose-coupling, the male and female parts or butts of which are constructed substantially as hereinbeforc described, and having a movable band or ring'iitted upon the female part or butt of the coupling itself, and constructed substantially as hereinbefore, to b o used in connection with catches K K of fig. 1, and the flange upon the inner end of the female part or butt.

And Ialso claim, as a part of my ,d evice, the small screws passing. through said ring, and extending into the grooves under' said ring, upon the body of the female part, for the purposeof indicating when the grooves or slots in the said ring are o'n a line with the siots in the female part or butt, all of which is constructed substan tially as hereinbefore described, substantially as and for the purposes hereinset forth.
